Let me also point out that carbon fiber composite doesn’t yield, it just fails catastrophically

I actually have a question about this because I saw someone on YouTube speaking about this two days before the debris was discovered (the channel is Sub Brief, and they were going through all the things wrong with the vessel and how it likely imploded).

With metal/steel/other alloys (forgive me, I'm not familiar with the engineering, hence my question), when they implode, it's straight up crushed, right? Like force on a tin can.

In the video I mentioned, the guy was saying that carbon fiber doesn't crack; it's like porcelain (I think he said, or another fragile material) and it just shatters completely.

So I've been curious about something. The implosion that this submersible suffered, what would it have looked like?

If the hull just shattered under pressure, would the implosion be more like hundreds of thousands of shattered pieces ripping apart everyone rather than "crush" them in the "traditional" sense (and they'd be immediately crushed anyway by the water pressure regardless)?

Or would the implosion still present itself more or less the same as it would with a steel(?) hull?

It feels almost worse if they were, for lack of a better term, shredded. I know that it would still be instantaneous, but it feels like... I don't know, much more visceral.

Whistleblower asked for non destructive examination of the material to understand its flaw structure

Do you know what would have been involved here? Some kind of imaging, I assume?

Thanks for the write up!

100% with you on the value of codes and standards. I used to work in a field that was very safe except for the rare occasions on which it was very unsafe, and we all learned not only what the regulations were, but why those regulations were in place. Having the reason explained usually killed any desire I might have had to break that regulation, which of course is why the explanations were part of the training process. "Don't do this thing that is likely to lead to extremely painful injuries" or "make sure to do this thing in order to keep the very expensive machine from breaking" are rules I am delighted to follow.

I read somewhere that Rush had wanted to be an astronaut, but hadn't made the grade for some reason. I wonder if it was because he would have endangered everyone around him if he had been involved in a mission.

“almost all sub accidents are the result of pilot error”.

But it was his error, and as far as I know, he also was the pilot, so...
